My Icom 746 Pro with 32 bit IF -based DSP also does a great job at noise
reduction. Even with that in place the Heil CSS
-further- removes noise in the audio..some which may have been induced past
the IF strip....

No antenna end noise reducer would catch that

I don't agree that Heil is taking any "hits" with the CSS. I also own an
AmCom Clear Speech Base Unit purchased about 3 years ago before Bob got
into
the development. It also did not come with a power supply and AmCom also
strongly recommended that one use a separate power supply due to potential
feedback issues. It cost me an additional $20 for a ps and ferrites and my
CSS is feedback free even on HF with 1KW.

Maybe it's a sign of the times, but I remember back when kits came with
everything needed and enough extras to accommodate a variety of
applications. If external power was required, suitable wall warts etc
were included, as well as pigtails to allow use of your existing station
power supply, and if RF shielding was required, the chokes would have
been in there too, usually in little plastic bags.
Since this device is basically a glorified tail end tone control, acting
on whatever gets all the way through the entire system, I'd prefer the
phased noise canceler someone else mentioned that zaps noise at the
antenna input. I checked and they are in about the same price range.
